【问题描述】：
谁能帮忙，我正在尝试隐藏/显示我的 html 表格列，我的表格在标题中有三行，需要隐藏/显示第二行的列以及包含的小行，我使用了一个示例在 Stackoverflow 中找到但仍然无法成功完成这项工作，我的代码如下：
$(function() {
// on init
$(".table-hideable .hide-col").each(HideColumnIndex);
// on click
$('.hide-column').click(HideColumnIndex)
function HideColumnIndex() {
var $el = $(this);
var $cell = $el.closest('th,td')
var $table = $cell.closest('table')
var colIndex = $cell[0].cellIndex + 1;
// find and hide col index
$table.find("tbody tr, thead tr")
.children(":nth-child(" + colIndex + ")")
.addClass('hide-col');
// show restore footer
$table.find(".footer-restore-columns").show()
}
// restore columns footer
$(".restore-columns").click(function(e) {
var $table = $(this).closest('table')
$table.find(".footer-restore-columns").hide()
$table.find("th, td")
.removeClass('hide-col');
})
$('[data-toggle="tooltip"]').tooltip({
trigger: 'hover'
})
}) body {
padding: 15px;
}
.table-hideable td,
.table-hideable th {
width: auto;
transition: width .5s, margin .5s;
}
.btn-condensed.btn-condensed {
padding: 0 5px;
box-shadow: none;
}
/* use class to have a little animation */
.hide-col {
width: 0px !important;
height: 0px !important;
display: block !important;
overflow: hidden !important;
margin: 0 !important;
padding: 0 !important;
border: none !important;
